The present invention discloses a novel aquatic product sorting machine. A structure of the novel aquatic product sorting machine comprises an aquatic product material feeding hopper, an alarm, an alarm bracket, an aquatic product sorting box, an aquatic product ice-melting and dampness-removing mechanism, a sorting box bracket, a sorting box controller, a first material discharging hopper, a second material discharging hopper, and a weighing and sorting room. The aquatic product material feeding hopper is connected with one side of an upper end surface of the aquatic product sorting box, thealarm bracket is connected with one side of the upper end surface of the aquatic product sorting box, the alarm is electrically connected with an upper end surface of the alarm bracket, the aquatic product ice-melting and dampness-removing mechanism is arranged on an inner surface of the aquatic product sorting box, and the weighing and sorting room is also arranged on an inner surface of the aquatic product sorting box. By arranging the aquatic product ice-melting and dampness-removing mechanism, the novel aquatic product sorting machine can automatically perform an ice-melting and dampness-removing treatment of aquatic products in use, prevents sorting effects of the device affected by different weight of the aquatic products after freezing, and is strong in practicability.
